I wrote an article on home coffee roasting for Tastebud last night. I’m a big fan of home roasting, and have been explaining it to a bunch of folks over the past couple of months. I thought it was worth a write up, and might be interesting to you techie folks. http://tastebudchicago.com/blog/roast-your-own-coffee/
I also added a couple of my roast notes. I have a stack of index cards I need to enter into the site, a bunch of wines, cheeses, and coffees. The teeny coffee list is at http://tastebudchicago.com/coffees/.
If you like coffee, and have a DIY sort of ethic, coffee roasting is probably right up your alley. Get up on it.
